So yesterday I changed password on ubuntu, but today I wanted to revert it so I entered user accounts and tried to change it, but sadly I could not. It told me password is not secure enough or something then i disabled log in options, but i want it back as it was

i had this problem before, but as i was running ubuntu off a usb i had made complete backups, i suggest you use windows to locate the syslinux folder and change syslinux.cfg to allow the boot menu, it explains:) and then press escape when booting ubuntu and seeing a purple screen

at this point i dont remember what to do but im sure the search box tells you, i remember seeing a forum on how to reset or change if you forget your password

I have no problem booting in the os i just press enter on the log in screen and it logs in no problem but in terminal i can not enter because it asks me password and I have no idea what it might be guess i gave to re-install
